What doesn't kill you makes you stronger, and selling a million albums makes you stronger still. Kelly Clarkson passed the million-sales mark for her Stronger album last week, according to Nielsen SoundScan. Stronger sold 8,000 copies last week to reach the milestone,

The album, released in October 2011, had been certified platinum by the Recording Industry Association of America in September 2012. It's the fourth platinum album of Clarkson's career, with 2004's Breakaway having sold more than 6 million copies.

Phillip Phillips had the top-selling album from an American Idol alumnus last week, as The World From the Side of the Moon remains in the top 10 of The Billboard 200 chart. Even assuming a traditional post-holiday sales slump, Phillips' debut should reach 500,000 in sales within the next week or two.

Album and track sales for several Idol and Idol-related albums and tracks follow.
